E-Instrumentation - An Innovation in Control Engineering:
(Innovative Project in Young Innovators Contest of International Institute of Technology)
Duration: January 2002 to March 2002
The aim of this project was to demonstrate a secured method of controlling a plant via internet.
The project work incuded included:
Simulation of an heat exchanger control loop
Demo of enabling the control of above mentioned simulation via Internet with three level security
Abstract for E-Instrumentation: An Innovation in Control Engineering
In the industry today, in remote automation i.e. for distributed control systems or SCADA systems, there are thousands of wire that has been routed kilometers from field to control system which costs lakhs of rupees to industries. The E-Instrumentation plan aims to reduced the number of wires to only few wires or even none (wireless), and also remove the barrier on limitation on distance of remote terminal and plant. E-instrumentation helps the plant supervisors and managers to access monitor and even control their plant anywhere in the world irrespective of the location of their plant and that too with secure communication from supervisor to plant.
The system consists of 3 subsystems as follows
Control System - takes care of the control of actual plant and also provide data to the interface system.
Interface System - consists of web server and hardware lock. Web server hosts the company site and is responsible for the communication between the remote user and the control system. Hardware lock provides the third level of the security.
Remote System - a computer anywhere in the world connected to the Internet.
Control System - since this project being a demo model, a simulation of Heat Exchanger loop was developed to act as the control system.
Interface System - the software for communication with the control system was developed on web server. The web server via parallel port activates the hardware lock system.
Security System - A 3 level security system as follows is provided in interface system
Level 1 - a usual username and password type as used in most email sites
Level 2 - at this level, user has to type a sequence of URLs in the address bar of the Explorer
Level 3 - when a user has passed the above 2 levels of the security, a hardware lock in the field is activated which generates and audio-visual alarm in and depending on the position of the key switch, the user is allowed or denied the access
If the user fails 3 times in providing the right information, then user is denied access.
The basic application of the system is to provide Remote Automation. As per plan to achieve this we have to install a web server in control room and then that computer is connected to Internet. But this system can be used to achieve the following target.
As we told earlier that e-instrumentation could reduce the wiring to few or even none this is how we can do it.
Present Remote Automation System:
In recent situation the wires from the field are routed to the control system, many hundreds and thousands of wire are routed to main controllers in the control room. This cost lacs of rupees and due to this the distance of control room and actual field is also limited because as distance increases the cost of wiring also increases.
Remote Automation with E-Instrumentation:
In this system, we can have main controllers in the field itself connected to the control computer and web server in the field itself and then this web server can be connected to a modem Ethernet line or may be a transreceiver. And end terminal i.e. can be anywhere will connect to the web server through Internet or Ethernet line or wireless transreceiver. So this reduces the wiring by thousand times and so is the cost reduced.
